Can Schrodinger's Cat Be Really a Quantum Touchstone?

It is revealed the invalidity of idea that famous Schrodinger's cat thought experiment can be a quantum touchstone. The arguments are: (i) probabilistic incorrectness in (over)rating subject, (ii) possibility imagining non-quantum scenarios but completely similar to (iii) lack ratified practical tests having genuine essence (i.e., non-counterfeit). So, aforesaid appears as simplistic exercise without any notable significance for physics.
